Definitions

• animal fiber such as wool is different in the quality and the extent of adhesion of impurities according to the site even in a sheet of fleece.
• animal fiber such as wool is different in the quality and the extent of adhesion of impurities according to the site even in a sheet of fleece.
• it should be classified into three or four grades to be used properly in efficient way in accordance with the object.
• it is scoured and then subjected to practical application processes such as carding.
• chemical treatments in the scouring step to remove impurities ( grease, sweat, dirt, etc. ) adhered on the animal fiber.
• a complex scouring process is applied by using chlorinated solvents and detergents.
• Such a scouring process has problems not only in operation but also in the waste disposal and damage of the fiber.
• the subject of the invention is to provide a method for physically and efficiently improving the scouring process and the milling property of animal fibers with no use of chemicals causing environmental pollution.
• the above-mentioned subject is solved by immersing an animal fiber in an aqueous bath containing inactive inorganic powder and treating it by ultrasonic wave.
• the inorganic powder used in the invention may be anyone inactive and stable form and the type is not restricted especially.
• sintered products of iron, manganese and the like, various ceramics, and minerals such as feldspar and the like may be used.
• powders of far-infrared ray-radiating ceramics e.g., zirconia type, alumina type and titania type ceramics
• zirconium carbonate and the like it is preferred that the powder is made to be spherical with no angle as far as possible by being, for example, crushed in a ball mill so as not to damage the fiber.
• the inorganic powder is preferred to have a diameter smaller than that of the fiber so as not to damage the fiber.
• the powder having a diameter of substantially not larger than 5 microns is preferably used.
• the ratio of the inorganic powder to water is not especially restricted, but generally it is preferred to be 5 ⁇ 60 : 100 by weight, particularly 10 ⁇ 50 : 100 by weight.
• the ratio is too low, the treating speed is lowered.
• the method Of ultrasonic treatment is for example such one in which the fiber is placed in a bath containing inorganic powder in water and ultrasonic wave is applied to it from upper and lower sides or upper, lower, right and left sides.
• the frequency is preferably not lower than 18 kilohertz, more preferably about 26 to 38 kilohertz.
• the upper and lower frequencies may be either same or different. When the frequencies are made different each other, the gap of waves is eliminated between the wave lengths and the treatment can be performed compactly in high speed.
• the extent of removal of the scales of the fiber surface can be set at an optional level by properly selecting the frequency of ultrasonic wave and treating period.
• the fiber can be treated in the state of yarns, felts and woven or knitted fabrics as well as raw fibers to optionally remove scales on the fiber surface to improve the dyeing property and shrink-resistance of the fiber. Resultantly the use of animal fibers becomes very broad.
• the product thus prepared was good in feeling and excellent in dyeing property, and allowed uniform dyeing easily.
• the shrink resistance was also highly improved.
• a felt of 15 cm square was placed and two ultrasonic wave generating plates were arranged respectively at a distance of 5 cm above and under the felt and ultrasonic wave was applied at a frequency of 38 kilohertz from upper side and a frequency of 26 kilohertz from lower side for 20 minutes.
• the product was completely free from scales and no significant unevenness was observed on the fiber surface even by a microphotograph of 2000 magnifications.
• a woolen fabric was treated in the same manner as in Example 1 to obtain a product very improved in both of feeling and shrink resistance and useful as a comfortable underwear.
• the resultant product had an improved dyeing property and was excellent in corrosion-resistance and shrink-resistance.
• the fine ceramic powder used was same as in Example 1.
